Abstract: Power amplifier apparatus comprising a power amplifier (1) having a signal output, and a power control feedback loop (3, 4, 5) for controlling the output signal power relative to a first power target signal (8). A saturation control loop (6, 7) is responsive to a parameter indicative of saturation of the power amplifier (1) for adjusting the output signal power to a level at which the power amplifier means is substantially not saturated. A power target variation module (11, 15, 16) operable when the first power target signal (8) is at or close to a value corresponding to saturation of the power amplifier means (1) applies to the power control loop (3 to 7) a modified power target signal (17) corresponding to a power target higher than the first power target signal (8) and at which the power amplifier means (1) saturates. The modified power target signal (17) causes the saturation control loop (6, 7) to react to saturation of the power amplifier means (1) adjusting the output signal power to a level at which the power amplifier means (1) operates substantially at its maximum power but not saturated.

Abstract: A monolithic RF amplifier circuit (10) suitable for use in the 0.8-2 GHz frequency range comprises, on-chip (12'), a gateable oscillator (24) running at about 2-5 times the amplifier input frequency or higher, coupled to a rectifier (30) and a low pass filter (34) for producing a DC signal which is fed via a bias/gain control circuit (46) to a bias/gain inputs (56, 58) of one or more amplification stages (60, 62) (e.g. GaAs FET) to provide bias therefore to ensure safe operation, and a priority control circuit (42) responsive to the bias. The priority control circuit (42) operates a power switch (18) that couples the amplification stages (60,62) to a power supply, only when bias is present on their bias/gain inputs (56,58) This protects the amplification stages (60,62) against overcurrent operation. A separate external port (68) to the bias/gain control circuit (46) adjusts the magnitude of the bias to permit amplifier gain and power output to be adjusted. By gating the oscillator ON and OFF, high speed burst mode operation of the amplifier is achieved.

Abstract: A power amplifier module comprises a power amplifier circuit having an output power level controlled by a power supply voltage. A power supply transistor controls the power supply to the power amplifier circuit from a drive signal which is received from a drive circuit. The drive circuit generates the drive signal in response to a power level input signal, which specifically may correspond to a power ramping for a GSM cellular communication system. The power amplifier module furthermore comprises a detection circuit which determines an operating characteristic of the power supply transistor. The operating characteristic is preferably a saturation characteristic. A control circuit controls the drive signal in response to the operating characteristic. The control circuit preferably controls the drive signal such that the power supply transistor does not enter the linear region for a Field Effect Transistor and the saturated region for a bipolar transistor.
